I've taken to using a little stress ball myself. Doesn't help much when i accidently break my nails (which happens often as a grocery worker) but it helps other times

It is the oral fixation that you are replacing with the seeds, same thing happens to smokers.

Thanks, I'll be sure to give this a shot when I'm able!

Sadly I'm alergic to sunflower oil

one of my friends used to bite his nails.
he quit using a special product- a transparent nail 'polish'- made with capsicum extract.
you know the stuff that makes hot peppers hot.

I'll have to give it a shot.

if I was a nailbiter, I'd think about it. I'll keep it in mind for others tho!

I don't bite my nails, but i chew on straws and toothpicks CONSTANTLY. It's a weird quirk of mine all my friends know about. There's a reason my sona is always drawn with something in his mouth.

I suppose I'm a nail biter, although it's never caused me any problems. I manage to keep them nice and even and I don't over do it. Probably happens a little more often when I'm anxious. It's not something I do all the time, but I also don't remember the last time I used a nail clipper for my finger nails. :T

I took up eating sunflower seeds and Roasted salted peanuts as a way to stress eat.
However, I tend to run out and the age-old habit doesn't go away. And for some reason, it doesn't affect my thumbs.
